Well right now i have a volitan lionfish(4"-5"), blue jaw trigger(4"), niger trigger(3"), mexican dragon eel(~20"), clown sweetlips(I know bad choice of fish, but found out after I had bought it). I plan on getting a radiata lionfish within this upcoming week. I really would like a grouper but dont know if it would be a good choice. What other fish would people recommend. I know I am nearing my max capacity but would like to know.
